Summary
Quantitative genetics is evolving into systems quantitative genetics, addressing complex traits with a new dynamic network model. This shift integrates systems biology principles for a deeper understanding of heritable phenotypes.
Area of Science:
- Life Sciences
- Genetics
- Systems Biology
Background:
- Classical and molecular quantitative genetics laid foundational theoretical frameworks.
- The advent of systems biology is prompting a paradigm shift in quantitative genetics.
- The trajectory of quantitative genetics beyond its classical and molecular phases remains an open question.
Purpose of the Study:
- To explore the potential development of quantitative genetics in the systems biology era.
- To define and discuss the emerging field of "systems quantitative genetics".
Main Methods:
- Perspective article discussing theoretical advancements.
- Conceptualization of a new dynamic network model for genetic analysis.
Main Results:
- Proposes "systems quantitative genetics" as a new discipline.
- Defines systems quantitative genetics as the study of bioalleles controlling heritable phenotypes of complex traits using a dynamic network model.
- Discusses related topics including genetical genomics and network model updates.
Conclusions:
- Quantitative genetics is poised to evolve into systems quantitative genetics.
- Systems quantitative genetics offers a novel framework for understanding complex traits.

02:02Genomics
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...
01:43Incomplete Dominance
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.
01:09Epistasis Analysis
Although Mendel chose seven unrelated traits in peas to study gene segregation, most traits involve multiple gene interactions that create a spectrum of phenotypes. When the interaction of various genes or alleles at different locations influences a phenotype, this is called epistasis. Epistasis often involves one gene masking or interfering with the expression of another (antagonistic epistasis). Epistasis often occurs when different genes are part of the same biochemical pathway. The...
01:25What is Population Genetics?
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.While some alleles of a given gene might be observed commonly, other variants...
01:23Behavioral Genetics and Its Designs
Behavior genetics explores how genetic inheritance influences human behavior. It focuses on how genes, passed from parents to offspring, contribute to the development of behavioral traits and tendencies. This branch of genetics seeks to understand the complex interplay between inherited genetic factors and environmental influences in shaping our behaviors.
The primary methodologies used in behavior genetics include family studies, twin studies, and adoption studies, each providing unique...

01:18Polygenic Traits
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...
